Fallout from bug 670023. Basically the same cause as bug 677646 had.

Alice, does it mean the installation doesn't work at all via D&D into the add-ons manager now?

(In reply to Henrik Skupin (:whimboo) from comment #3) > Alice, does it mean the installation doesn't work at all via D&D into the > add-ons manager now? Installation is successfully performed. However, the following problem exists. a. Compatible issue arrow panel does not appear if incompatible version xpi is dropped. b. Installed Successfully arrow panel does not appear when Install Now button clicked in Software Installation dialog for restartless addon. c. Restart Now arrow panel does not appear when Install Now button clicked in Software Installation dialog for olds tyle addon.

Thanks Alice. Sounds we should track it for Firefox 8 and 9.

---------------------------------[ Triage Comment ]--------------------------------- We need to track this for Firefox 8 to see how bad an issue it is and if it needs to be fixed before ship. CCing Asa and Boriss as well.

Drag and drop of an XPI is an edge case I don't think we should worry too much about. The crazy overwhelming majority of our add-on users get add-ons by other means than downloading XPIs, locating them on their hard drives, and dragging them on to the Add-ons manager in Firefox.

Oh update. The install window did pop but it popped under. So i didnt see it. So I saw a bunch of "Software Installtion" pop ups in the task bar.

Can you file a separate bug for that? Thanks.

ok sure :)

I'm very new to writing extensions and am getting this precisely this error. But I'm such an blithering fool that I cannot find on this site an explanation of how to use the attachments to repair the bug. Are these files I need add somewhere? Please reply as if I'm a complete idiot.
